So just find a cite to explain anything about how that is done. While a normal EtherNet interface does not have that type of built in test capability, there are examples of test equipment available, that can be manually applied to a line, which will test for all variety of wiring errors. Using a Time Domain Reflectometer it is possible to locate specific faults such as the impedance bump from a broken wire (or for that matter from too sharp a bend in the wire). > Guess some folks haven't been keeping up. Lets go back to the basic question, and restate the facts: The specific color and or pair number in a CAT5, CAT5E, or CAT6 cable is not significant. If different pairs are wired to the appropriate pins for a particular data pair the connecting interface will still function exactly as it should. What that means in practical terms is that a cable can be wired as T568A or T568B (or another "standard") as long as both ends use the same standard. -- Floyd L.
